IMPROVEMENT IN WRENCH.

TO WI'IOM IT'MAY CONGERN:

' Bc it known that I, JOSEPH A. TALEY, of Somerville, inthe county of Middlesex, and State of Massachusette, have invented certain new and useful improvementsiin Wrenches; and ,I hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanying drawings.

,My invention essentially consists of a wrench infwhich two sets of jaws arecombined with the wrench-bar or shank, the one set being rectangular with respect to the said shank o'n which they are mounted, and the other being inclined atan angle of sixty degrees, or thereabouts, to the same, so that with the same wrench nuts of any shape maybe readily caught` and held. The rectangular jaws, for instance, are fitted to grasp a square or oetagonal nut, while the inclined er sloping jaws on the opposite side of the central bar are adapted for hexagonalior other irregularly-shaped nuts not readily grasped by the rectangular jaws.

The nature of my invention will be readily comprehended by reference to the drawings, in which#- Figure 1 is a front elevation, and

Figure 2 aside elevation of my improved wrench.

The upper jaws B 0I the wrench are stationary, forming the head of the bar or shank E, which is secured by ordinary means in the handleG. The jaws ALB are located diametrically opposite each other upon the shank, the jaw standing at right angles tothe same, while the inclination of the jaw B with respect to the shank: is Yabout sixty degrees, or any suitable angle required by the form of the nut it is intended to grasp. The lower and movable jaws C D, Awhich correspond with the fixed-jaws A B, respectively, slide upon the bar E, and at thei-rbase carry a pair of jaws or ears, a a, which grasp the head b of a rosette, K, which is capable of being moved up and down upon thc scrcw-shank E in the usual manner. The lower jaws proper, O D, which are formed in onc piece, rest upon bearings c e', which are supported on a base, d, the latter encircling the shank and holding the rcsette.` v

This arrangement of the jaws is at once efective and simple, and is/productive of4 advantages which will be readily apparent..A Y In one wrench I combine the peculiar-advantages possessed by a rectangularly-jawcd wrench, as well as by one with sloping jaws, or those set at a greater. or less angle than ninety degrees with respect to the shank; thus making itl not only more convenient for use, and better adapted for all purposes for which wrenches are ordinarily employed, but cheaper in the end than either of the kinds of wrenches referred to.

It willof course be understood that the details of construction herein described may be. varied, without departing from the principle of my invention, any other suitable means being employed with. equally goed results to securethe rosette to the jaws, and to move them up and down upon the wrench-bar. The lower jaws, also, may be made stationary'and the upper jaws movable, as is often done in wrenches of ordinary construction.

Having described my invention, and the manner in which the same is or may be carried into eifect, what I claim, and desire to secure by Letters Patent, isp As a new article of manufacture, the wrench herein described, provided with twol sets of jaws, the one rectangular with respect to the shank of the said wrench, the other sloping,'or at an inclination to the same as and for the purposes herein shown and Vset forth. v

, In testimony whereof I h av'signed my name to this specification before two subscribing witnesses.
